Exercise Should Be Prescribed for Brain Health, Researchers Say

Live Poll

Would you make time for at least 75 minutes of exercise weekly for your mental health?

Canadian researchers reviewed evidence on exercise and mental health and concluded that physical activity should be prescribed like a drug for brain health and severe mental illness. As little as 75 minutes of moderate activity per week appeared to bring significant benefits.

Why it matters

People with schizophrenia and other severe mental health problems typically have higher rates of sedentary behaviour, weight-related heart conditions and early death. Physical activity has been linked to improved memory and reduced symptoms of depression, offering a low-cost addition to care across Canada.

The review drew on a body of studies rather than a single trial, and as little as 75 minutes of moderate weekly activity appeared beneficial, compared with the 150-minute NHS guideline for adults aged 19 to 64. Evidence that exercise improves working memory and attention in people with schizophrenia is promising, but the cognition findings rest on a limited set of modest trials.

The details

Researchers from the University of Ottawa and the University of Toronto reviewed evidence on exercise and mental health. Most patients should start with a low-risk activity and increase volume and intensity gradually, while those with frailty or respiratory conditions may need extra support.

Health Landscape

The NHS recommends 150 minutes of moderate activity weekly for adults aged 19 to 64, and this review suggests a far smaller dose may help people with severe mental illness. It positions exercise alongside medication as a treatment tool in mental health care.

Canadians living with schizophrenia or other severe mental illness may find that regular moderate activity, starting with low-risk options, fits into their care plan. Anyone with frailty or a respiratory condition should seek extra support before increasing activity.

The takeaway

Even about 75 minutes of moderate movement a week may offer real benefits for memory and mood, so starting small and building gradually is a practical step. Talk with a health provider before beginning if you live with a serious mental illness or a chronic condition.
